Heraclitus is one of the greatest Buddhas of the world. In western philosophy his name is not part of the mainstream. The mainstream consists of Socrates, Plato, Aristotle, Kant, Hegel, Bertrand Russell, Wittgenstein, Moore. Heraclitus is something like an outsider for the simple reason that he is one of the greatest mystics. What Aristotle only thinks, Heraclitus knows. What Wittgenstein only thinks, Heraclitus experiences.
